J GLASS-TANK.

' Application filed April 10,

To all whom it may concern."

'Be it known that 1', WALTER A. Jones, a citizen of the United States, residing at Morgantown, in the county of Monongalia and State of est Virginia, have invented new and useful Improvements in Glass- Tanks, of which the following is a specification.

This invention is an improved method and means forprotecting the clay blocks or piers of a glass kiln from disintegration un der the intense heat of the molten glass,

The blocks or piers which are employed to separate a series of drawing chambers of a glasstank, are usually constructed of very high'grade clay, but experience has shown that they will melt off, and are dis integrated-anddestroyed by the intense heat and; attrition of the molten glass. This destructionbi a; constant source of expense, both, becauseof the necessity of frequentl' -replacing thef-parts, and because the tan must be routof use While the repairs are being made.g.This melting off of the piers "is 25 also objectionable because it affects the quality ofthe'glass by reasonof the impurities deposited in the bath and thcinequalities inpthe temperaturecansed thereby. One of theobjectsof the present invention is to overcome the foregoing objection by making provision for the protection of the piers andother similar parts, which are wholly or partially surrounded by molten glass, and to prolong the life thereof. A further object 13 to provide means for maintaining the" exposed portions at a sufficiently low! temperature to ofv'ferconie the melting action of the molten glass. A further object isto provide means aforassisting in the maintaining of a uniform tempera-hire of the molten glass.

[The invention will be hereinafter fully set,forth"and particularly pointed out in the 0 arms.

at 11. The said tank is provided with a up of tongued and gI'OOVEdCIaYBblOCkS 14,

15, 16, and 17, almost entirely surrounded by molten glass at temperatures ranging from 1900 to 2250 Fahrenheit. The piers are built upon a bottom 18, as shown.

The respective piers are protected by water containers arranged to 'maintain. the piers at a temperature sufiieiently low to overcome orcounteract the destroying effect.

of the intense heat of the .'molten glass. Each container is made of any-suitable material, and of any required shape, and coniprises a metallic casing 19; located in a suit- 1 v v able bore formed in the bottom 18, and the blocks of the'piers 12." The said container extends to the top of the-pier: and its upper end is closed by a cap 20, referably b a screw threadconnection. T e'lower en the container extends well below the bottom Patented Dec. 18, 1917.

18 and is closed by a cap 21, perforated to receive a ater inlet pipe/'22 and a water outlet or overflow pipe\23, 'the inlet pi e being provided with perforations 24. it ill be noted that the inlet end of the outlet pipe islocated close to the up'per end of the container. nected with supply mains 25" one between each pair of piers 12, and eac inlet pipe is rovided with an independent valve 26.

he outlet pipes are preferably also con- ;nected in pairs and lead back to the reservoir or to such other point as may be desired. i

In lieu of arranging the inlet pipes in pairs as described, they may all be supplied from a single main 27, as illustrated at tlie left hand end of Fig. 2.

In practice the water is supplied to the inlet pipes 22 by suitable pumps, 01'' other in'lpelling means, not shown, and is discharged into each of the containers through the perforations 2 t, filling. the container 19, and flowing out of the pipe 23. By locating the inlet end of the pipe 23 close to the top of the container, the latter is kept substantially full of Water at all times. By locating the containers as shown the piers are kept sullicicntly cool to maintain their shape, and to prevent the corners'being worn off or destroyed by the intense heat and attrition oi the molten glass. The containers extend The water inletpipes are con-- Well below the bottom oi the tank so that all of the connections are readily accessible should repairs or replacement be necessary.
